Ancient Period: None, don't know much if anything about the Ancient Period to make a guess
Classical Period: I have two...
Cyrus II: Built the Persian state from the ground up, practically made Persia the empire in which later emperors and later dynasties aspire to replicate.
Aurelian: Restorer of the World, reunited the empire under force of arms. Sure, Diocletian was the one responsible for ending the Crisis of the Third Century, but Aurelian could've probably managed to have done more had he not been assassinated.
Medieval Period: Going to pick a not so obvious one, Constantine V, the Isaurian. Pretty respectable in his own right, despite being called the "Dung-Named"
Renaissance Period: Gustavus Adolphus, the Lion of the North. Hero of the Thirty Years War, probably the reason why that one EUIV achievement exists.
Industrial Period: Abdulmecid I, despite his reign seeing nationalist sentiment which ultimately doomed his multi-ethnic empire and ultimately the House of Osman as a ruling dynasty, did help promote much needed reforms to an Ottoman Empire. Can't say the "Sick Man of Europe" didn't try to make itself better during his reign.
